Introduction to Metamorphic Rocks, Rock Metamorphism, …

Hence, metamorphic processes occur in a temperature continuum from surface temperature upward. However, the low-temperature limit of metamorphism has been arbitrarily set to about 150–200 °C in this book (Fig. 1.3 ) and most of the presented phase-diagrams show phase equilibria above 200 or 300 °C.

The Rock Cycle – Physical Geology

The rock cycle is the set of processes by which Earth materials change from one form to another over time. The concept of uniformitarianism, which says that the same Earth processes at work today have occurred throughout geologic time, helped develop the idea of the rock cycle in the 1700s. Processes in the rock cycle occur at many different …

In the SD limestone, the amount of water that can penetrate by capillarity is lower than on the other limestone samples. This indicates a highly modified porous network by the weathering. Two phenomena can occur at the same time: the filling of the porosity by new-formed products and the transformation of the free porosity into trapped porosity.
